Question: A small charged sphere (treat as a point charge) with charge q and mass m is orbiting around a LONG wire (treat as infinite wire)

A small charged sphere (treat as a point charge) with charge q and mass m is orbiting around a LONG wire (treat as infinite wire) with a uniform linear charge density . The radius of the circular orbit is 5 cm. The speed of charge is 3 m/s. **There is no gravity in this problem. What is the charge density on the wire? Find . Knowns: m = 1x10^-5kg v = 3 m/s q = -1x10^-10C R = 0.05m
